some circumstances lead to suffocation.
This warning applies to most models of
flow generators.
The exhaust vent flow is lower at lower
•
mask pressures (see Pressure/Flow
Curve— section A). If the mask
pressure during expiration is too low,
there may not be enough exhaust vent
flow to completely flush the air delivery
hose of exhaled air before the start of
the next inspiration.
The mask should not be worn if the anti-
•
asphyxia valve membrane is damaged or
missing. If the valve membrane is
damaged, distorted or torn, it should be
replaced with a new valve membrane.

•
at increased risk of gastric regurgitation.
The mask must be cleaned and
•
disinfected/sterilized if it is used

If oxygen is used with the flow
•
generator, the oxygen flow must be
turned off when the flow generator is
not operating.
Explanation of the Warning: When the
flow generator is not in operation and
the oxygen flow is left on, oxygen
delivered into the air delivery tubing
may accumulate within the flow
generator enclosure and create a risk of
fire. This applies to most types of flow
generators.
Oxygen supports combustion.
•
Oxygen should not be used while
you are smoking or in the presence
of an open flame.
Always ensure airflow is being
•
generated by the device before the
oxygen supply is turned on.
Always turn the oxygen supply off
•
before stopping the airflow from the
device.
Please refrain from smoking while
•
oxygen is in use.
Using a mask may cause tooth, gum or
•
jaw soreness or aggravate an existing
dental condition. If symptoms occur,
consult your physician or dentist.
Note:
At a fixed flow rate of supplemental
oxygen flow, the inhaled oxygen concentration
will vary, depending on the pressure settings,
patient breathing pattern, mask selection, and
the leak rate.
